To all whom it may concern:

Be it known that I, HENRY N. FREN'DRESS, o Dunleith, in the county of JoDaviess and State of Illinois, have invented a new and usefulimprovement in Barbs for'Wire-Fences, of which the following is aspecification:

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish improved barbs forwire-fence, which shall be simple in construction, inexpensive inmanufacture, and reliable in use, keeping theirplaces securely.

The invention consists in the barbs formed by cutting thin sheet metalinto diamond form, slitting them from the acute angles nearly to thecenter, and bending the prongs at each end at an angle with each otherto adapt them to be twisted into a two'strand wire-cord, as hereinafterfully described.

The barbs A are cut intodiamond shape, as shown in Fig. 3, and are slit from their acute anglesnearly to their centers, so as to form four prongs. The four prongs arethen bent at the inner ends of the slits, the two prongs at each end ofthe diamond-shaped blank being bent from each other at an angle, so thatthe two prongs upon each side may be parallel with each other,
